LCD Display Double Height Characters

Workshopshed
Workshopshed
22 May 2013

As part of a project to build a digital rotary table I've been experimenting with double height characters.

 

The Circuit


The circuit for this is an I2C LCD display wired to the standard I2C pins on the Arduino and a linear 10K potentiometer with the wiper connected to the analogue input 0 on the Aruduino.

In the code

 

The setup function creates a few blocky custom characters.

An array stores the defintions of the numbers 0-9 with regards to which of those custom characters need to be displayed.

The loop then reads the input and then displays the results in the large characters.
